BOSTON (AP) — The state's dominant health insurer is under fire for a roughly $11 million compensation package given to its former chief executive who resigned last March after five years.

According to documents filed with the state Tuesday, former Blue Cross Blue Shield of Massachusetts CEO Cleve Killingsworth collected $1.4 million in severance and $7.4 million in additional compensation last year. He is scheduled to receive nearly $3 million more over the next two years.

The package was given at a time of skyrocketing health care costs and poor performance by the nonprofit insurer, which has 3 million subscribers.

Ethan Rome of the Washington-based advocacy group Health Care for America Now, told the Boston Herald the compensation package is "unconscionable."

Killingsworth told The Boston Globe the payment was "consistent with my contract."
